VLC snapshot command error

[ChayMahajj]

Hello everyone,

I am using vlc rpi distro for bullseye.
I would like to take a snapshot of the video.
I am using cvlc command line to play the video and I don't have a GUI interface in my system.
My goal is to take a snapshot of the Video in the end using a command line.
I used this cmd:
cvlc trailer.mp4 --rate=1 --video-filter=scene --vout=dummy --scene-format=png --scene-prefix=snapshot --scene-path=/home/ --scene-replace
But various errors apears :

I will be thankfull if you provide me with a solution or explanation.

Chayma.

Just to check - after all that output does it then work or does it crash/return to the command-line without creating a snapshot?
You could try adding --codec avcodec --avcodec-hw none which should force s/w decode though it won't prevent a lot of spurious output.
